I have skoda yeti MY13. recently i noticed that the reversing sensors stopped working. I used to have graphic pic on Bolero and beeping sounds when the reverse gear was selected. now I have no sounds no pic on bolero screen. Today I put the reverse gear in without starting the ignition, just to see which sensor was faulty. All of the sensors were working but still no beeping sounds and no graphic pic on Bolero.  Is there any way to get the sensors fixed without taking it to a dealer?
